FM & Waveshape Oscillator

Pizza is a compact digital oscillator with powerful wave shaping applied to FM synthesis. Pizza offers a ton of flavor in a compact form, and it grants superb access with the assignable CTRL knob and CV, while its 3 different outputs allow for high patch flexibility. The unique take on FM synthesis combined with waveshaping offers a vast sonic palette while staying intuitive. Pizza is perfect for hybrid synthesis! Waveshaping on MAIN output gives you the world of additive techniques, while the PULSE and OSC OUT speak the subtractive language where mixing the outputs into a filter will sound massive!

Because of its digital nature, Pizza does not have to be tuned, and its approach to tuning is different. You only go to the Tune mode when you actually need to. Otherwise, the PITCH knob serves as either octave transpose or detune. Pizza is built around 3 internal oscillators - the Main Oscillator, which can be phase modulated (FM) and wave folded, and two modulating oscillators. The modulating oscillators are the Octave (sub) Oscillator, with dedicated output, and the Ratio Oscillator, serving more advanced FM duties. Both have square-sine-saw wave shape control for more timbral variety and can ring modulate the main oscillator.
FM INDEX crossfader applies phase modulation to the Main oscillator either with the Ratio Oscillator or the Octave Oscillator (can be replaced by an external signal). The INDEX MOD attenuverter for the CV controls the FM INDEX.

The CTRL knob and CV input are assignable and allow you to gain more access to the oscillator core. It can be assigned to control: linear FM, exponential FM (global, Octave, or Ratio osc.), octave, detune, modulator ratio selection, wave-shaping, wave-folding, ring modulation, or built-in bipolar VCA.

The EXT input allows direct phase modulation of the Main Oscillator.
The V/OCT input can be easily calibrated to match correctly with any source. Just play note C corresponding to 0V and C two octaves higher (2V), and you are ready to be perfectly in tune. You can also quantize the V/OCT input.
